3 Claims.

and the details of construction are not here illustrated excepting to the extent necessary to show the improvement. In the accompanying drawing:

Figure l. is a view similar to Figure 6 of the above named patent showing the sheave and connecting parts in side elevation and the rope lock partly in section; Figure 2 is a section on the line i. of Figure 1; Figure 3 is a perspective view of the removable rope gripping shoe; and Figure 4 is a section through a modified form thereof.

Referring to the drawing, 4 is the main hoisting rope by which the load is elevated. The rope runs over a sheave 5 and beneath a rope clamp t pivoted at l eccentrically to the sheave 5. By means fully illustrated in the above patent, the rope clamp is held in an elevated and inoperative position while the load is being raised. When the load has been sufficiently elevated the rope clamp may be released to come into operative engagement with the rope either by hand or when the load has reached its topmost position by engagement with a trip member 8.

When a given hay carrier is continuously used under conditions where the hand release is generally employed very little difiiculty is experienced with wearing of the rope. This is because the rope clamp engages different portions of the rope on difierent operations, and the wear is very well distributed.

On the other hand, when carriers of the type in question are used with barns having small doors high up in the hay mow, the hand release is in many instances never used and the automatic release always operates when the load has been pulled to extreme upper position. Under such circumstances the rope clamp constantly engaging the rope in the same position Wears it with undue rapidity. Numerous efiorts have been made to overcome this trouble, but none of the remedies have been entirely satisfactory.

I have discovered that the difficulty can be completely remedied in a very simple manner and by a device applicable to the very large number of carriers of this general type in use.

To this end I provide a shoe 9 which lies inside the rope clamp 6. The shoe is provided on its outer face with two metal clips I0 each having at its two ends alfixing hooks ll. These hooks can be bent down over the edges of the rope clamp 6 so as to hold the shoe quite firmly in position.

The shoe is made of yielding fibrous material. I have found the woven brake band material commonly employed on some automobiles satisfactory for the purpose, and I have also found that fibrous material cut from an automobile tire is quite satisfactory. The important point is that the material shall be free from sharp or hard 10 cutting surfaces and shall be sufficiently yielding to grip well around the strands of the rope. It should also yield sufficiently to be pressed firmly against the rope lock 6.

In the form of attachment shown in Figure 4 the shoe has on its rear a plate I2, an extension [3 of which is brought over the rope clamp 6. A tongue M is thrust through a slot in the plate i2, and is gripped between the tines of a cotter pin l5 which is then rotated to coil the tongue as shown and make a firm look.

It is very desirable to have the shoe easily removable so as to be replaceable as it wears and because such shoes can be supplied at a low price so as greatly to increase the utility of the hay carriers now in use. When made so removable the shoe should be sufficiently tough and sufficiently reinforced by its fiber content to Withstand the rather severe strains to which it is subjected in use. Apparently a considerable variation in the nature of the rope-engaging surface is permissible. When the brake band material above alluded to is employed fiber material thereof can contact directly with the rope. On the other hand, the presence of a rubber layer adjacent the rope is equally if not somewhat more efiective in reducing wear.

While I have shown a hay carrier of the type in which the improvement was worked out, other types within the claims may be similarly im proved.

I claim as new and desire to secure by Letters Patent:

1. In a hay carrier of the type wherein a hoisting rope is gripped by a locking device and where in the locking device is automatically set by the rise of the load so as repeatedly to engage and hold the rope in the same place while the rope is substantially stationary and without substantial slipping of the rope, a rope engaging shoe secured to the inner face of the locking device, the shoe being largely composed of fibrous material and being sufficiently yielding to conform to the irregularities of the rope without substantially breaking the rope fibers.

2. In a hay carrier of the type wherein a hoisting rope is gripped by a locking device and wherein the locking device is automatically set by the rise of the load so as repeatedly to engage and hold the rope in the same place while the rope is substantially stationary and without substantial slipping of the rope, a rope engaging shoe secured to the inner face of the locking device by metal clips attached to the shoe and hooked over the edges of the locking device, the shoe being largely composed of fibrous material and being sufliciently yielding to conform to the irregularities of the rope without substantially breaking the rope fibers.

3. In a hay carrier of the type wherein a hoisting rope is gripped by a locking device and wherein the locking device is automatically released by the rise of the load so as repeatedly to engage the rope in the same place, a rope engaging shoe, a plate on the rear thereof between the same and the locking device, a slotted extension on one end of the plate, a tongue on the other end extended through the slot, a cotter pin between whose tines the tongue is gripped at its end and around which it is coiled, the aforesaid shoe being largely composed of fibrous material and being sufficiently yielding to fit into the irregularities of the rope without substantially breaking the rope fibers.
